cauline in 3–6 pairs, sessile, reduced distally, blade lanceolate, narrowly elliptic, or oblanceolate, 2–4 cm × 2–8 mm, apex ± acute, glandular-puberulent throughout.
sessile or narrowed at base into pseudopetiole, blade pubescent on both surfaces;
proximal with blade lanceolate and oblanceolate, broadest distally or distal often reduced, cauline longest near mid stem, blade linear to lanceolate or elliptic, 1.5–10 cm × 2–30 mm.
usually with solitary terminal flower, sometimes cymose, to 8-flowered, open.
from 1-flowered to simple dichotomy to compound and 3–5–many-flowered with elongate branches;
bracts small, linear-lanceolate, or resembling leaves.
erect or angled near tip with flowers slightly nodding, 1–3 times longer than calyx, glandular-puberulent, often densely so.
elongate, much exceeding calyx.
calyx prominently 10-veined, campanulate, not contracted proximally around carpophore, 15–20 × 4–8 mm, papery, margins dentate, veins parallel, usually purple tinged, with pale commissures;
lobes ovate, 3–5 mm, glandular-puberulent, midrib triangular, margins purple tinged, broad, membranous, apex obtuse;
corolla bright pink, clawed, claw equaling calyx, broad and ligulate but abruptly contracted into limb, limb broadly cuneate, shallowly to deeply 2–4-lobed, 5–15 mm, lobes broad or narrow, appendages absent or to 2 mm, margins erose;
stamens slightly longer than corolla claw;
stigmas 3(–5), slightly longer than corolla claw.
calyx green, 10-veined, broadly tubular, 12–25 × 4–8 mm in flower, narrower towards base, middle broadening to 6–13 mm in fruit, narrower at both ends, pubescent, glandular, lobes lanceolate, 2.5–5 mm, margins membranous or not, apex ± obtuse;
corolla scarlet, clawed, claw equaling or longer than calyx, limb lobed, often deeply so, lobes 4–6, linear, lanceolate, or oblong, small lateral teeth may be present, 6–15 mm, appendages inconspicuous, 1–2 mm, dentate;
stamens longer than corolla claw but shorter than lobes;
stigmas 3, equaling corolla.
equaling calyx, opening by 6 (or 8 or 10) lanceolate teeth;
carpophore 1–2.5 mm.
oblong to ovoid or broadly tubular, equaling calyx, opening by 6 ascending teeth;
carpophore 2–4 mm.
brown, broadly reniform, flattened, 2–2.5 mm, rugose, more coarsely so on margins.
reddish brown, broadly reniform, 1.7–2.3 mm, sides tuberculate, margins papillate.

Silene petersonii
Silene laciniata
Of conservation concern.
This beautiful alpine species is variable with respect to density of pubescence, flower size, and petal structure. As this variation occurs both within and among populations, little useful purpose is served by giving names to it. The Nevada population, which is the basis for the name Silene clokeyi, is interfertile (A. R. Kruckeberg 1961) with populations in Utah (the basis for the name S. petersonii). Accordingly, a single species is recognized here without infraspecific taxa.

Subspecies 3 (3 in the flora).
The large, beautiful scarlet flowers of Silene laciniata are bird- and butterfly-pollinated. The species occurs in three forms. Subspecies laciniata has narrow leaves, much-branched and many-flowered, open inflorescences, and oblong capsules. Subspecies californica has ovate to lanceolate leaves, few-flowered inflorescences, and ovoid capsules. These two entities both occur in California and Mexico. Although they are usually distinguishable, apparent intermediates occur. The third entity is subsp. greggii, which occurs in Arizona, southwestern Texas, and Mexico. It combines characters of the other two subspecies, having broader leaves, a branched and many-flowered open inflorescence, and a capsule of intermediate shape.
